The summons were issued to Arbaaz after prominent bookie Sonu Jalan alias Sonu Batla -- who reportedly has links with various mafia dons, including absconding Dawood Ibrahim Kaskar -- was arrested sometime ago and interrogated by the AEC sleuths in connection with the IPL scam, he added.

"The case investigations are going on since the past five-six years and could involve amounts of over Rs 500-600 crore. We want to find out from Arbaaz what was his role in the entire matter," said Kothmire who is probing the matter.
